Groupthink

Groupthink

When in group settings, we are often influenced by the thoughts, feelings, and behaviors around us. Groupthink is another phenomenon of conformity where modification of the opinions of members in a group aligns with what they believe is the group consensus (Janis, 1972). In such situations, the group often takes action that individuals would not perform outside the group setting because groups make more extreme decisions than individuals do. Moreover, groupthink can hinder opposing trains of...

Group Polarization

Group Polarization

Group polarization is the strengthening of an original group attitude following the discussion of views within a group (Teger & Pruitt, 1967). That is, if a group initially favors a viewpoint, after discussion the group consensus is likely a stronger endorsement of the viewpoint. Conversely, if the group was initially opposed to a viewpoint, group discussion would likely lead to stronger opposition.

Confirmation Biases

Confirmation Biases

The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?

Conformity

Conformity

Conformity is the change in a person’s behavior to go along with the group, even if that person does not agree with the group.

In- and Out-Groups

In- and Out-Groups

People all belong to a gender, race, age, and social economic group. These groups provide a powerful source of our identity and self-esteem (Tajfel & Turner, 1979) and serve as our in-groups. An in-group is a group that we identify with or see ourselves as belonging to.

Conservation of Small Populations

Conservation of Small Populations

Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less likely to...

Area of Science:

Social Psychology
Behavioral Economics
Decision Sciences

Background:

Collective decision-making often involves conflicting interests, risking costly failures.
Groups may be vulnerable to manipulation by strongly opinionated minorities, especially when members are uninformed or have weak preferences.

Purpose of the Study:

To investigate how uninformed individuals influence group decision-making dynamics.
To determine if uninformed individuals can mitigate manipulation by extremist minorities in collective choice scenarios.

Main Methods:

Employed theoretical modeling to explore group dynamics under varying conditions.
Conducted experimental studies to validate theoretical predictions regarding minority influence and uninformed participation.

Main Results:

A strongly opinionated minority can indeed dictate group choice under certain conditions.
The presence of uninformed individuals significantly inhibits minority manipulation, shifting control back to the numerical majority.

Conclusions:

Uninformed individuals play a crucial role in maintaining democratic consensus within groups.
The participation of uninformed members is vital for overcoming internal conflict and informational limitations in group decision-making.
